You can transform epoch time into javascript Date objects in the Date
object constructor:
var date = new Date(epochTime);
which you can use to input the epoch time into a DataTable; or, if you
already have epoch time in your DataTable, you can use a DataView (or the
"view" parameter of a ChartWrapper) to handle the transform and output Date
objects for your chart:
var view = new google.visualization.DataView(data);
view.setColumns([{
type: 'date',
label: 'date column label',
calc: function (dt, row) {
return new Date(dt.getValue(row, 0)); // assumes column 0 is the
epoch time
}
}, 1 /*[, 2 [, 3 [, etc]]]*/);
